作者自1979年以来在调查和鉴定浙江省大麦病害的过程中,发现了8种国内尚未报道过的真菌病害。现将它们的分布、发生以及症状特点和病原形态等分别简述如下: 一、大麦灰霉病 此病在嘉兴、桐乡、德清、富阳、余杭、萧山及杭州郊区等地均有发生。在春季低温多雨年份可造成一定的损失。如1983年春杭嘉湖地区低温阴雨,大麦穗发病率达15.7～31.2％,千粒重降低5.1～8.7％。
Since 1979, during the process of investigation and identification of the disease of barley in Zhejiang Province, 8 kinds of fungal diseases not yet reported in China have been found. Now their distribution, occurrence and characteristics of symptoms and pathogen morphology are summarized as follows: First, the gray mold disease of barley in Jiaxing, Tongxiang, Deqing, Fuyang, Yuhang, Xiaoshan and Hangzhou suburbs have occurred. Low temperature in the spring rainy years can cause some losses. For example, in the cold, rainy and rainy regions of Jiaxing-Huzhou in Spring-Hangzhou in 1983, the incidence of barley spikes was 15.7-31.2% and the grain weight was reduced by 5.1-8.7%.
